Water readily dissolves most polar compounds true or false
Each statements are mentioned true or false below: 1. False. 2. True. 3. False. 4. True. 5. False. 6. True. 7. True. 8. False. 9. False. 10. True. Explanation: 1. In a water molecule, the oxygen atoms being more electronegative, pulls the Electron pool more towards itself. So the molecule becomes somewhat polar. 2. Those solutions in which water molecule is the solvent are called aqueous solutions. 3. In a molecule which have equal shares of electron among all atoms, the molecule is apolar or non polar. Polar molecules do have more electron density in some atom and less in others. 4. Water molecule is itself somewhat polar in nature. This helps the other polar molecule dissolve in water readily. 5. NaCl is an ionic compound. It is formed of sodium cations and chlorine anions. 6. In ionic compounds, according to electronegativity, the cations loose electrons and anions gain electrons. 7. Water molecule in a solution helps to withdraw the negative ions of the solute apart from positive ions because of its polarity. 8. Like dissolves like refers to the fact that polar compounds dissolve in polar solvents and apolar solute dissolves in apolar solvents. 9. Oils are apolar in nature, so dissolves in apolar solvents like benzene etc. 10. Solubility refers to the amount of solute dissolving in a particular amount of solvent at a particular temperature and pressure. So more the number, more is the rate of solution.
See explanation for details. Explanation: In the water molecule. electrons are equally shared by hydrogen atoms and oxygen atoms- false In a polar covalent bond, electrons are unequally shared by the bonding atoms due to differences in electro negativity of the atoms. solutions for which water is the solvent are called aqueous solutions- true .if electrons are shared equally between atoms that compose a molecule, that molecule is said to be polar-false If electrons are equally shared between bonding atoms in a covalent bond, the molecule is nonpolar. A typical example is a diatomic gas such as Cl2. water readily dissolves most polar compounds- true water interacts with polar solutes via its dipoles. Hence water is a polar solvent. table salt, NaCL, is a molecular compound- false Table salt is not a molecular compound. It is an ionic compound. In an ionic compound, one or more atoms loses electrons, and one or more atoms gains electrons-true In solution, the charged regions of water molecules can pull a(n) ionic compound apart- true. When ionic substances are dissolved in water they are hydrated and pulled apart by the dipole in water. Chemists say “like dissolves like”. this means that dissolution tends to occur when the solid and the solute are similar in nature- true Polar solutes dissolve in polar solvents while non polar solutes dissolve in nonpolar solvents. Most oils tend to dissolve best in non polar solvents- true This is because ions are mostly nonpolar substances solubility tells you how fast a solute will dissolve- false Solubility tells you the amount of solute that will dissolve in a solvent at a particular temperature
It’s true water does readily dissolve most polar compounds because it is the universal solvent.
The answer is false, I hope this helps.
